Why is everyone so fixated on this? Do you really think Treyarch spent THAT much time putting hidden messages and etc into zombies and etc when they don't even spend that much time patching, making, or improving zombies or zombie maps? I just personally think that this is something that's too extra for them. I don't think they would go through all of this just for people to find them. Treyarch makes games, not calculus quizzes.
